I tried to do chi square test for the following observed frequencies --------------------------------------------------------------------------------------------- A B A 8 4 B 12 10
R gave the following output: ------------------------------------------------------------------------------------------- Pearson's Chi-squared test with Yates' continuity correction data: M X-squared = 0.10349, df = 1, p-value = 0.7477 Warning message: In chisq.test(M) : Chi-squared approximation may be incorrect --------------------------------------------------------------------------------------------------------------- Whether this result can be relied or we have to use Fishers exact test ?
